Мой метод form_valid не работает должным образом

Я работал в проекте и мне трудно понять, почему мой метод form_valid не работает для ProfileCreateView. Я создал модель профиля для пользователя. Вот код:

# views.py
from django.views.generic import CreateView
from .models import UserProfile
from django.urls import reverse_lazy

class ProfileCreateView(CreateView):
   model = UserProfile
   template_name = "profile/profile_create.html"
   fields = ('profile_picture', 'bio', 'occupation', 'hobbies', 'date_of_birth')
   success_url = reverse_lazy("login")

   def form_valid(self, form):
      form.instance.author = self.request.user
      return super().form_valid(form)

  # template
  {% extends 'base.html' %}

  {% block title %}Create Your Profile{% endblock title %}
  {% load crispy_forms_tags %}
  {% block content %}
  <div class="container border border-success rounded mt-4 ">
  <h2 class="display-6 fst-italic mt-3 mb-3">Create Your Profile</h2>
  <form method="post" enctype="multipart/form-data">
      {% csrf_token %}
      {{ form|crispy}}

     <button type="submit" class="btn btn-outline-primary mt-4 mb-4">Create my 
        profile</button>
    </form>

   {% endblock content %}

   # models.py
   from django.db import models
   from django.contrib.auth import get_user_model
   import uuid
   from django.core.files.storage import FileSystemStorage


   class UserProfile(models.Model):
      author = models.OneToOneField(get_user_model(), on_delete=models.CASCADE)
      profile_picture = models.ImageField(upload_to='images/')
      id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
      bio = models.TextField(blank=True)
      occupation = models.CharField(max_length=100)
      hobbies = models.TextField(blank=True)
      date_of_birth = models.TimeField()

      def __str__(self):
           return self.author.username + ("'s profile")

пожалуйста, подскажите, как правильно это сделать!

from django.contrib.auth.forms import UserCreationForm

class ProfileCreateView(CreateView):
   template_name = "profile/profile_create.html"
   form_class = UserCreationForm
   success_url = reverse_lazy("login")

    def form_valid(self, form):
        result = super(ProfileCreateView,
                        self).form_valid(form)
        
        cd = form.cleaned_data
        user = authenticate(username=cd['username'],
                            password=cd['password1'])
        login(self.request, user)
        return result
